Enum NameMatcher 

#[non_exhaustive]
pub enum NameMatcher {
    Exact,
    AsciiCaseInsensitive,
}

Controls how flag names are matched when parsing.

Why #[non_exhaustive]

NameMatcher is only used as an input parameter to parsing APIs, never returned as a result. #[non_exhaustive] is appropriate here because new matcher variants can then be added in minor releases without breaking callers.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Exact

Matches flag names exactly.

AsciiCaseInsensitive

Matches flag names using ASCII case-insensitive comparison.

Implementations

impl NameMatcher

pub fn matches(self, given: &str, expected: &str) -> bool

impl Ord for NameMatcher

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
